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If there is any reason to suspect that the safety of the unit has been affected then it must be immediately withdrawn from use and precautionary measures taken in order to prevent any further use of in the hazardous area.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.
With deep discharge and short circuit protection
and max. 1,0 Ampere Halogen at least. 3,75 Volt and max. 0,75 Ampere

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 unscre­wing - 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 indi­cate 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 char­ging station, the emergency light mode function is automatically activated. If the power supply to the charging station is then inter­rupted, 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 auto­matically reverts to trickle charge mode.
The LED indicates the following operating status:
Constant red: no handlamp / contact Constant green: charging in process Shortly before transition to trickle charging: constant green and flashing red Constant red and green: 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 Ex­hazardous 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: + terminal Black: - 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 gran­ting 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 los­ses 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 effec­tivity or enforcement of any other part of this guarantee should be unaffected by such claims.
