Instruction Manual  
H-251 A  
 
1. Introduction  
Providing an intense bright inspection light beam, the intrinsically  
safe rechargeable handlamp type H-251A is certified for use in  
Ex-hazardous areas classified as either Zone 1 or 2 and also  
Zone 21 or 22 according to IEC/CENELEC.  
2. Safety information  
Safe operation of the equipment is maintained providing that all  
instructions and warnings contained in this manual are fully  
observed.  
In case of doubt (due to translation and/or printing errors)  
reference should be made to the original German instruction  
manual.  
3. Faults and damage  
If there is any reason to suspect that the safety of the unit has  
been affected then it must be immediately withdrawn from use and  
precautionary measures taken in order to prevent any further use  
of in the hazardous area.  
The safety and integrity of the unit may be compromised by, for  
example:  
• External damage to the housing  
• Exposure to excessive loads  
• Incorrect storage of the unit  
• Damage sustained in transit  
• Correct certification is illegible  
• Functioning errors occur  
• The permitted limitations are exceeded  
13  
 
4. Safety regulations  
The use of the intrinsically safe H-251A meets the requirements of  
the regulations providing that the user observes and applies the  
requirements as laid down in the regulations and that improper  
and incorrect use of the unit is avoided.  
• The device must not be opened within the Ex-hazardous area.  
• The battery must only be changed outside of the Ex-hazardous  
· area.  
• The use of any other type of battery pack in the Ex-hazardous ·  
· area is not permitted.  
• The battery pack may only be charged outside of the Ex-  
· hazardous area by using either units type C-251 HVE or  
· C-251 LV.  
• The use of any other type of battery is strictly forbidden in that it  
· will invalidate the Ex-Data certification and presents a safety risk.  
• Only batteries supplied by ECOM are permitted.

7. Operating instructions  
7.1. Handlamp  
Please read through the following operating instructions in order to  
help enable the optimisation of all functions of the handlamp type  
H-251A.  
For your own information and safety please read the advice on the  
following pages.  
7.1.1. Before use  
Before use in the Ex-hazardous area, ensure that the handlamp  
head is screwed fully closed to the main casing. The handlamp  
can now be switched on and off with the sliding switch.  
15  
 
7.1.2. Opening  
Warning: Do not open the handlamp within the Ex-hazardous area.  
Before opening, switch to OFF.  
The handlamp head is removed by turning anticlockwise from the  
main casing – please note, that as the handlamp head is fitted with  
a high integrity seal, this action can be difficult to start. To replace  
the handlamp head, reverse the procedure – ensuring that the  
handlamp head is screwed fully closed.  
7.1.3. Bulb replacement  
With the handlamp head removed the bulb is accessed by unscre-  
wing - in an anticlockwise direction - the bulb retention socket.  
Please ensure that only correctly specified bulbs are used.  
7.1.4. Battery replacement  
When the battery recharging capacity is becoming exhausted and  
needs replacing only batteries as specified by ECOM can be used.  
With the handlamp head removed the battery pack is removed by  
sliding it out of the cavity of the main casing.  
Replace in reverse procedure – ensuring that the contacts are  
clean.  
7.1.5. Battery charging  
After engaging the handlamp into the charging station, LED’s indi-  
cate the status and condition of operation. The handlamp can be  
removed from the charging station at any time.  
7.1.6. Emergency light mode  
When the handlamp is switched on and then engaged in the char-  
ging station, the emergency light mode function is automatically  
activated. If the power supply to the charging station is then inter-  
rupted, the handlamp switches on automatically - for a duration of  
approximately 7 hours (when fully charged). Likewise, when then  
removed from the charging station the handlamp switches on  
automatically.  
16  
 
7.2. Charging station  
The main switch for the charging station is located on the back of  
the unit. After switching on the handlamp, the charging process  
begins immediately. When charging is completed, the unit auto-  
matically reverts to trickle charge mode.  
The LED indicates the following operating status:  
Constant red:  
Constant green:  
no handlamp / contact  
charging in process  
Shortly before transition  
to trickle charging:  
Constant red and green:  
constant green and flashing red  
trickle charging  
The batteries must be fully recharged at least once every 6  
months.  
Please note: only use ECOM charging equipment when charging  
ECOM handlamps.  
Ambient temperature Ta: +10…+25 deg C.  
Only operate in dry, well-ventilated rooms, outside of the Ex-  
hazardous area.  
There are two different types of charging stations available for the  
H-251 A.  
7.2.1. C – 251 HV  
This charging station is designed for a supply voltage of 220-240  
Volts AC with 50-60 Hz. A voltage of 100-120 AC Volts can be  
switched manually to 50-60Hz.  
90% battery charging capacity is reached after 6-7 hours.  
After approximately 9 hours of charging, the battery should be  
completely recharged.  
WARNING - an incorrect voltage can damage the equipment,  
therefore please take care to ensure that the correct voltage is  
selected.  
17  
 
7.2.2. C – 251 LV  
This charging station is designed for a supply voltage of 12-32  
Volts DC. Complete recharging using a 12-Volt DC supply should  
be completed in approximately 20-24 hours, using a 24 Volts DC  
supply reduces this time to approximately 10-12 hours.  
Correct connection of the cable wires is as follows:  
Red:  
Black:  
+ terminal  
- terminal  
8. Repairs  
The general terms and conditions of ELEX V apply to repair work.  
The manufacturer must carry out the repair work in order to check  
for the safe functioning of the protective circuits.  
9. Cleaning  
The equipment should only be cleaned using a cloth or sponge  
dampened with water. The use of cleaning solutions or scouring  
agents is not advised.  
10. Guarantee and liability  
The instrument parts and functions are guaranteed for two years,  
starting from the date of delivery. This guarantee remains valid if  
defective components are submitted. We reserve the right to  
exchange, modify or repair the equipment.  
The company ECOM Rolf Nied GmbH is responsible for the gran-  
ting of the guarantee. It takes no responsibility for damages,  
expenses or losses resulting from the use or purchase of the  
equipment. Neither is ECOM liable for damages, expenses or los-  
ses arising from any special or subsequent damages.  
Further, any use other than that as described in section 1 is not  
permitted. ECOM is not liable for any damages resulting from any  
differing or excessive use. The user carries this risk alone.  
18  
 
In those countries where the restriction of a legal guarantee (e.g.  
the exclusion or limitation of subsequent damage) is not permitted,  
it could be that the above mentioned limitations and exclusions are  
not valid for each purchase. Should any clause of this guarantee  
be found ineffective or unacceptable before a court, then the effec-  
tivity or enforcement of any other part of this guarantee should be  
unaffected by such claims.
